mountaindewguy Posted May 1, 2006 Share Posted May 1, 2006 ok i might be able to snag a JDM b16 head off an SIR locally, i THINK its OBD1 (pretty sure) lets sayit is OBD1 and odds are in my favor.. will this be a good head for my LSVTEC? also, are the springs and retainers the same as a USDM spec? because obviously with it being older and unknown miles i want to replace them. thanks!

..SSR.. Posted May 1, 2006 Share Posted May 1, 2006 It sounds like this is just a very mild build so whats it matter which VTEC head you use? Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 1, 2006 Author Share Posted May 1, 2006 i just mean i didn't know if there was any differences in the SIR heads or the regular b16 heads, or will they both perform the same. i know next to nothin about the b16 heads, and also if the springs and retainers are all the same? cause i was gonna prolly get crower springs and retainers w/ stage 2 cams. i might be able to pick this engine up for 3 or 400 bucks believe it or not. some old guy that owns a business across the street bought the whole engine and tranny for his nephew, his nephew only needed the tranny so now he's stuck with the engine and has been for the past year. so i told a guy that works there, jokingly that is, to tell him 300 bucks and i'll take it, so he did, and i guess the old man said "sounds reasonable, i'll think about it" i went over there today to find out if its OBD1 or 0, but he didn't have the papers with him today. is there any way to tell by looking at the engine?

cranny Posted May 2, 2006 Share Posted May 2, 2006 type r i beleve is the only head out of the 1.8 B series that has different springs and retainers. Link to comment Share on other sites More sharing options...
SolLesHonda Posted May 2, 2006 Share Posted May 2, 2006 You'd be correct. Type R valvetrain is totally different. Link to comment Share on other sites More sharing options...
cranny Posted May 2, 2006 Share Posted May 2, 2006 although you can strap type r springs and retainers in any other B series DOHC VTEC head. cams as well. Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 2, 2006 Author Share Posted May 2, 2006 question, and i need it answered ASAP. that b16 above is out of a SIR, i know that, but is there any way to tell if its OBD1 or OBD0 by the engine? the guy lost the papers..?

..SSR.. Posted May 3, 2006 Share Posted May 3, 2006 If it is OBDO trash it. Those heads flow like poo. Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 3, 2006 Author Share Posted May 3, 2006 i don't know if it is or not, thats what i was saying. is there a way to tell the difference in looks, sensors, anything? it doesn't have manifolds or dizzy. Link to comment Share on other sites More sharing options...
cranny Posted May 3, 2006 Share Posted May 3, 2006 i dont understand how your associating obd anything with the head. what does its obd version have to do with how much air the head flows? all B16 engines since like 89 have same power output so i dont get your point here ssr. if hes got a B16 head than it dont matter what year it is its good. B16A (89-91 SiR , 160 horse. also 92-95 SiR 170 horse), B16A1(160 horse SiR) , and B16A4(170 horse SiRII) . Link to comment Share on other sites More sharing options...
..SSR.. Posted May 3, 2006 Share Posted May 3, 2006 OBD0 B16 heads are the worst flowing B16 heads. Don't believe me, go put some on a flow bench. Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 3, 2006 Author Share Posted May 3, 2006 he's right. and the reason cranny, if i can pick this motor up for cheaper than dirt i want to either sell it for more, or use the head for my LSVTEC, and down the road maybe use the block in a build.

cranny Posted May 3, 2006 Share Posted May 3, 2006 It sounds like this is just a very mild build so whats it matter which VTEC head you use? If it is OBDO trash it. Those heads flow like poo that my friend is known as a contradiction. i still dont know what your talkin about. any difference in the porting of the heads is bound to be very mild if any.USDM B16 engines all have same horsepower rating, so take it from there. how can one head flow any better without making more power is what im sayin? and once again ill say that the OBD version has nothing to do with the head. you can say this year head is better than this one, but you cant say obd "this" head is better than obd "this" head cause obd has nothing to do with the head or what it can flow. so if your gonna pass up on a pre 92 B16 head cause you think it flows crapty your as crazy as a crap house rat cause there the same.

90IntegraC1 Posted May 3, 2006 Share Posted May 3, 2006 just gonna put in my $.02 here...not like i know what im talking about though. Doesn't OBD0, OBD1, and OBD2 refer to what years the car was made? 0=oldest, 2=newest? but you would think honda did some modifications to the head of their b16 motor between OBD0 years and OBD2 years wouldn't you? So, the newer heads might actually flow better then the older heads, therefore making ..ssr.. correct. I'm not trying to correct you Cranny, im just trying to put 2 and 2 together, you know?

mountaindewguy Posted May 4, 2006 Author Share Posted May 4, 2006 i agree. plus wouldn't there be a wiring issue using an OBD2 block, OBD0 head, and OBD1 computer? regardless, i only want it if its OBD1, because if i didn't use the head i'd resell it, and an OBD0 engine has considerably less value. and cranny, its not a USDM engine, its JDM so does anyone know a way to tell the dif. by examining the engine? thanks!

CleanGSR Posted May 4, 2006 Share Posted May 4, 2006 No. OBD does not refer to when the car was made. OBD is On Board Diagnostics and has changed basically due to emissions over the years. Link to comment Share on other sites More sharing options...
90IntegraC1 Posted May 4, 2006 Share Posted May 4, 2006 oh ok, didn't think i was right. i just though obd0 is the older honda's and obd2 is newer honda's. oh well, can't be right about everything... Link to comment Share on other sites More sharing options...
..SSR.. Posted May 4, 2006 Share Posted May 4, 2006 He wouldn't be putting a VTEC head on if he doesn't care about performance. Since he does care, he should get a OBD-I or higher head. Get an OBD0 and OBDI head and have them flowed. You'll see the difference. The difference is not all in the ports. Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 4, 2006 Author Share Posted May 4, 2006 ...anyone know how to tell the difference? i would like to find out tomorrow if posible, thanks! Link to comment Share on other sites More sharing options...
cranny Posted May 4, 2006 Share Posted May 4, 2006 run the numbers it will tell you the year. and it dont matter what year it is , if its a good head than buy it and run it. Link to comment Share on other sites More sharing options...
mountaindewguy Posted May 4, 2006 Author Share Posted May 4, 2006 where do i run the numbers at? its a JDM engine, so it may be a bit hard... Link to comment Share on other sites More sharing options...
cranny Posted May 4, 2006 Share Posted May 4, 2006 honda is honda dude. dont make it complicated. even though its a JDM model , the head is the exact same as we have here. EXACTLY. the year of the head dont really matter. you can run any dis. on it you want. they all have same specs , same firing order so on so forth.
